Some nights you do not want a recipe, you want dinner. This is that dinner. A packet of egg noodles, a head of garlic you were going to use eventually, and a splash of soy is genuinely all it takes.
The one step worth doing properly is the sizzling oil. Heat it until it just begins to shimmer, then pour it over the garlic and spring onion in the bowl. It blooms instantly, the kitchen smells extraordinary, and that is your sauce made.
Add chilli oil to taste, a fried egg on top if you are hungry, or a handful of leftover roast chicken. Ten minutes from cupboard to bowl, and better than most things you could have ordered.
